In addition to the other provisions of this subpart, C&DRFs shall be designed in accordance with the following:

1. (1) Contents of plans. The engineering plans shall include a detailed description of the facility’s design that must address the following:

   1. (A)

      1. (i) Ingress and egress.
      2. (ii) The plans should show the flow of traffic into and out of the facility.
      3. (iii) Separate entrances should be provided for incoming or outgoing trucks if necessary and a separate entrance provided for employees, customers, and visitors;

   2. (B)

      1. (i) Unloading and loading areas.
      2. (ii) Loading and unloading areas must be adequate in size and design to facilitate efficient loading and unloading from collection vehicles and the unobstructed movement of vehicles;

   3. (C)

      1. (i) Processing, tipping, sorting, and treatment areas.
      2. (ii) Such areas for incoming materials must be located within an engineered pad having a durable surface designed for the types of vehicles and loading activities permitted at the site.
      3. (iii) The pad shall be maintained to prevent rutting and ponding of water;
   4. (D) Weighing or measuring all solid waste accepted at the facility and residue, bypass waste, and recyclables recovered and identification of the means to accomplish same;
   5. (E) Sufficient storage areas for the incoming solid waste;
   6. (F) Exhaust systems may be required for enclosed areas;
   7. (G) Truck and wheel curbs provided to prevent backing into pits while unloading;
   8. (H) Identification of the types of materials to be stored and the location or locations of temporary on-site storage areas;
   9. (I) Adequate storage capacity is required at the facility for all waste handled and for those recyclables that will be stored before being removed;
   10. (J) If the facility is equipped with mechanical processors, a design that must maximize worker safety and be capable of minimizing the potential for, and the effects from, explosions; and

   11. (K)

       1. (i) Adequate facilities and equipment shall be provided for the periodic wash down of all processing, tipping, sorting, storage, and compaction areas.
       2. (ii) Floor drains, collection troughs, curbs, drainage breaks, or other suitable drainage structures shall be provided as needed to collect and route all wash down water and other liquids from the processing, tipping, sorting, storage, and compaction areas to a sanitary sewer or permitted on-site facilities for treatment;

2. (2) Contents of specifications.

   1. (A) Specifications must include any features of the construction and operation which are not described in other sections of this subpart.
   2. (B) Also included with the specifications should be any applicable design calculations that were used to calculate storage capacities, process volumes, system capacities, etc.;

3. (3) Contents of engineering narrative. An engineering narrative shall be furnished that describes the facility design including:

   1. (A) How the facility design meets the requirements of this subpart; and

   2. (B)

      1. (i) A description of the overall operation and a functional description of all processing equipment to be used, with design criteria and anticipated performance.
      2. (ii) There must be sufficient description in the narrative to understand the flow of solid waste and the associated operations when considering the recyclables handling and recovery facility as a whole; and
4. (4) On-site roads. On-site roads must be passable by loaded collection and transfer vehicles in all weather conditions.
